Julian Hyde commented on CALCITE-647:
-------------------------------------
I've made further updates to my branch.
I tried to use Base64Variants but I decided it's not a good idea. Because
Base64Variant does not expose an encode method the only way to encode byte[] to
base64 string is to use JsonValue annotation. I'd rather be in control of
converting values to a serializable form (because I want to do the same for
java.sql.Date, java.util.Date, java.sql.Timestamp).

> After the result are deserialized from JSON on remote side, the object is not
> with it's original type, forcing casing of box type Long on Integer raise

> For all box number, it will type cast to Number and extract using the Number
> method instead.
